Abstract

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine, when involved in a multimedia broadcast or multicast service, a set of parameters relating to the state of the wireless communication device. In some aspects, the wireless communication device may determine to decode a signal associated with the multimedia broadcast or multicast service during a measurement gap based at least in part on the set of parameters. In some aspects, the measurement gap may be a gap configured for performing an intra-radio access technology (IRAT) or inter-frequency cell measurement.

First claim

What is claimed is:

1. A method for wireless communication, comprising:
determining, by a user equipment (UE) involved in a multimedia broadcast or multicast service, a set of parameters relating to a state of the UE;
determining, by the UE, to decode an evolved multimedia broadcast multicast service (eMBMS) signal during a measurement gap based at least in part on the set of parameters,
wherein the measurement gap is a gap configured for performing an intra-radio access technology (IRAT) or inter-frequency cell measurement; and

decoding, by the UE, during the measurement gap, the eMBMS signal based at least in part on determining to decode the eMBMS signal.

2. The method of claim 1 , further comprising:
performing, during another measurement gap, the IRAT or the inter-frequency cell measurement based at least in part on another set of parameters related to another state of the UE.

3. The method of claim 2 , further comprising:
performing the IRAT or the inter-frequency cell measurement based at least in part on monitoring one or more neighbor cells of a serving cell of the UE.

4. The method of claim 1 ,
wherein decoding the eMBMS signal comprises:
decoding a physical multicast channel (PMCH) of the eMBMS signal.

5. The method of claim 1 , wherein the set of parameters includes at least two of:
a mobility state of the UE,
a signal to noise ratio (SNR) associated with a serving cell of the UE,
a block error rate (BLER) associated with an uplink or a downlink channel associated with the UE, or
a unicast data activity state of the UE.

6. The method of claim 5 , further comprising:
determining the mobility state of the UE based at least in part on a Doppler shift of the eMBMS signal.

7. The method of claim 5 , wherein the unicast data activity state of the UE relates to at least one of:
a browsing activity,
a file transfer protocol (FTP) throughput,
a packet data convergence protocol (PDCP) protocol data unit (PDU) size, or
a physical downlink control channel (PDCCH) downlink or uplink data count.

8. The method of claim 1 , wherein determining to decode the eMBMS signal is based at least in part on the set of parameters satisfying a set of thresholds.

9. A device for wireless communication, comprising:
a memory; and
one or more processors operatively coupled to the memory, the one or more processors configured to:
determine, when involved in a multimedia broadcast or multicast service, a set of parameters relating to a state of the device;
determine to decode an evolved multimedia broadcast multicast service (eMBMS) signal during a measurement gap based at least in part on the set of parameters,
wherein the measurement gap is a gap configured for performing an intra-radio access technology (IRAT) or inter-frequency cell measurement; and

decode, during the measurement gap, the eMBMS signal based at least in part on determining to decode the eMBMS signal.

10. The device of claim 9 , wherein the one or more processors are further configured to:
perform, during another measurement gap, the IRAT or the inter-frequency cell measurement based at least in part on another set of parameters related to another state of the device.

11. The device of claim 10 , wherein the one or more processors are further configured to:
